These SeaDog Line rail brackets are the bee’s knees for mounting things to your boat rails – great for solar panels, drink holders, canvas work, cockpit tables and so on.
We use them as the basis for our Metz antenna rail mount. They come with shims for mounting on 3/4″ (20mm) and 1″ (25mm) diameter rail, without the shims they fit 1 1/4″ (32mm) rails. Heavy duty nylon construction and stainless fittings – the thumb screw is held captive when the bracket is open. An excellent product that does exactly what it claims to do.
